Squat: mainly practice thigh muscles and gluteus maximus.
Action: Hold the dumbbell with both hands and put it on one side of your body, or put the dumbbell slightly above your shoulders for smooth control. Feet naturally open about shoulder width, feet slightly open, chest out, waist and back tightened. Kneel and squat down to the lowest position, and then the thighs are forced to contract and squat down to recover.
